These application tips and suggestions will help extend motor life in these hostile environments.If you have a motor application that involves operation in a wet or damp environment, you should know the proper choice of motor enclosure, the correct location of weep holes, and, in some cases, the use of an auxiliary heating device or system to warm the motor during nonoperating

A motor soft starter is a device used with AC electrical motors to temporarily reduce the load and torque in the power train and electric current surge of the motor during start-up. This reduces the mechanical stress on the motor and shaft, as well as the electrodynamic stresses on the attached power cables and electrical distribution network, extending the lifespan of the system.
